It sould like you could express what you want as follows:
If one of my special (~ ... ~) tags is found inside an HTML tag, replace that whole HTML tag with my special tag. Otherwise leave it alone.
In that case the following code should do the trick: 
$data =~ s/<[^<>]*?(\(~ .*? ~\))[^<>]*?>/$1/g;

That is a character-class consisting of not > or <. The perlre documentation has more details on how this works. My RE works by looking for the opening < of an HTML tag, then 0 or more non < > characters, then the special tag, then 0 or more non < > characters, then the > that closes the original HTML tag.
